encoding: add 'leftside' argument into 'trim' to switch trimming side

progress: use 'encoding.colwidth' to get column width of output line correctly Before this patch, 'progress' extension applies 'len' on byte sequence to get column width of it, but it causes incorrect result, when length of byte sequence and columns in display are different from each other in multi-byte characters. This patch uses 'encoding.colwidth' to get column width of output line correctly, even if it contains multi-byte characters.

progress: use 'encoding.trim' to trim output line correctly Before this patch, 'progress' extension trims output line by directly slicing byte sequence, but it may split at intermediate multi-byte sequence. This patch uses 'encoding.trim' to trim output line correctly, even if it contains multi-byte characters. "rm -f loop.pyc" before changing "loop.py" in "test-progress.t" ensures that re-compilation of "loop.py", even if "loop.py" and "loop.pyc" have same timestamp in seconds.

histedit: use 'util.ellipsis' to trim description of each changesets Before this patch, trimming description of each changesets in histedit may split at intermediate multi-byte sequence. This patch uses 'util.ellipsis' to trim description of each changesets instead of directly slicing byte sequence. Even though 'util.ellipsis' adds '...' as ellipsis when specified string is trimmed (= this changes result of trimming), this patch uses it, because: - it can be used without any additional 'import', and - ellipsis seems to be better than just trimming, for usability

util: replace 'ellipsis' implementation by 'encoding.trim' Before this patch, 'util.ellipsis' tried to avoid splitting at intermediate multi-byte sequence, but its implementation was incorrect. Internal function '_ellipsis' trims specified unicode sequence not at most maxlength 'columns in display', but at most maxlength number of 'unicode characters'. def _ellipsis(text, maxlength): if len(text) <= maxlength: return text, False else: return "%s..." % (text[:maxlength - 3]), True In many encodings, number of unicode characters can be different from columns in display. This patch replaces 'ellipsis' implementation by 'encoding.trim', which can trim string at most maxlength columns in display correctly, even though specified string contains multi-byte characters. '_ellipsis' is removed in this patch, because it is referred only from 'ellipsis'.

encoding: add 'trim' to trim multi-byte characters at most specified columns Newly added 'trim' is used to trim multi-byte characters at most specified columns correctly: directly slicing byte sequence should be replaced with 'encoding.trim', because the former may split at intermediate multi-byte sequence. Slicing unicode sequence ('uslice') and concatenation with ellipsis ('concat') are defined as function, to make enhancement in subsequent patch easier.

bugzilla: stop trying to cache setup across hook invocation In the context of standalone Hg receiving a set of incoming changes, it makes sense for the Bugzilla module to cache basic setup to avoid reconnecting to Bugzilla for each change. After processing the changes, Hg will exit and so the connection is short-lived. But this doesn't work too well when used from a long-lived environment such as hgweb or Kallithea where, for example, the connection can time out. So take the simple approach, abandon the cache and do the basic setup on each call. This fixes current problems with Kallithea.

strip: drop -b/--backup option (BC) This option had very limited utility and counterintuitive behavior and collided unfortunately with the much later -B option. Normally we would no-op such a feature so as to avoid annoying existing scripts. However, we have to weigh that against the silent misbehavior that results when users mistakenly intended to use -B: because -b takes no arg, the bookmark gets interpreted as a normal revision, and gets stripped without removing the associated bookmark, while also not backing up the revision in question. A no-op behavior or warning would only remove the latter half of the misadventure. The only users I can find of this feature were using it in error and have since stopped. The few (if any) remaining users of this feature would be better served by --no-backup.

purge: add options for deleting only files or only directories

shelve: accept '--edit' like other commands creating new changeset After this patch, users can invoke editor for the commit message by '--edit' option regardless of '--message'.

shelve: refactor option combination check to easily add new ones Before this patch, the name of a newly added option had to be added into each string that was passed to the "checkopt()" internal function: these are white-space-separated list of un-acceptable option names (= "black list" for the specified "opt"). This new option had to be added into multiple strings because each option could belong to only one action of "create", "cleanup", "delete" or "list". In addition to this redundancy, each string passed to "checkopt()" was already too long to include a new one. This patch refactors option combination check to make it easier to add a new option in a subsequent patch. New "checkopt()" only takes one action ("cleanup", "delete" or "list"), and checks whether all explicitly activated options are allowed for it or not (if specified action is activated in "opts"). The "date" entry is listed in "allowables", but commented out, because: - "date" shouldn't be checked for test checking "date" causes unexpected failure of "test-shelve.t", because "run-test.py" puts "[default] shelve = --date '0 0'" into hgrc. - explicitly listing it can advertise that ignoring it is intentional This patch doesn't choose "white list" for the specified "opt", to avoid treating global options.

test-extension: add check for 'hg version -v' listing enabled extensions

version: show enabled extensions (issue4209) This code is based by hg-versions extension (GPLv2) by Markus Zapke-Gruendemann <info@keimlink.de> http://mercurial.selenic.com/wiki/VersionsExtension

strip: remove bookmarks after strip succeed (issue4295) In case we have revs to strip, delete the bookmark after the strip succeeds, not beforehand as we might still abort due to dirty working directory, etc.

templater: introduce word function This function allows returning only the nth "word" from a string. By default a string is split as by Python's split() function default, but an optional third parameter can also override what string the string is split by.

committablectx: move __contains__ into workingctx This was mistakenly moved from workingctx to committablectx in 9d56a3359011. Since the method is querying the dirstate, the only logical place is for it to reside is in workingctx.

memctx: explicitly set substate to None In d2743be1bb06, memctx was changed to inherit from committablectx, this in turn added the 'substate' property to memctx. It turns out that the newcommitphase method tested for this property: def newcommitphase(ui, ctx): commitphase = phases.newcommitphase(ui) substate = getattr(ctx, "substate", None) if not substate: return commitphase Currently, memctx isn't ready to handle substates, nor removed files, so we explicitly must set substate=None to get the old behavior back. In the future, we can decide how memctx should play with substate. For now, this fixes third-party extensions and some internal code dealing with subrepos.

bookmarks: avoid deleting primary bookmarks on rebase Prior to this, doing "hg rebase -s @foo -d @" would delete @, which is obviously wrong: a primary bookmark should never be automatically deleted. This change blocks the deletion, but doesn't yet properly clean up the divergence: @ should replace @foo.

bugzilla: correct config documentation error The config documentation specifies the wrong access method in the XMLRPC+email configuration.
